I went to the f body gathering in Bowling Green this weekend. While we were there I decided to see what I could get the SS to
run at Beech Bend.
I had decent reaction times, worst was .665 and best was .585 but the stock Goodyears with 26K on them left A LOT to be desired! My 60 ft times were from a best of 2.45 to a worst of 2.57. Now here comes the killer, my best ET was 14.189!
Somebody please help me, the track is too far to make another trip anytime soon, and new tires are not an option right now, what kind of times should those MPH run? I know this is a hard question to answer, heck I saw people running upper 13s and not break 100MPH. Just give me some ideas based on the reaction times, MPH and WITH TRACTION! I swear my car hooks better than that on the street! I never break traction on the 3rd 4th shift on the street but I did there on the first run!
DUH, I guess I should have put my MPH in too huh? My best mph
was 104.91.

 

With a 2.0 60 foot...lets assume 13.4 is possible

 

Remember with those crappy 60' times you will have a much higher mph at the end of the track.

 

Hey a_z28_vance, how come crappy 60ft times would give me a higher mph? Just curious.

 

See sig, and that's not the best 60' yet, I'm sure.

 

Well after headers and a cat removal my car did manage a 13.28@104.91 with a 2.07 60' time. I did have a granatelli maf. and a borla cat back. The LT1's are awesome given the ability to breath,

a_Z28 is right. If you spin off the line, you run a higher mph. I'm not exactly sure why, but it's a fact. Another thing is, you can't compare an automatic car to a manual trans car. Automatics will almost always run a quicker time at a slower mph. For example, on slicks my '94 Z28 convertible (A4) ran a 12.85 @ 105.1 mph because I had a 1.77 60 ft time. My '02 Z28 (M6) ran a 12.82 @ 112 mph on a 2.06 60 ft time on street tires. Even on slicks, I wouldn't be able to get a 1.77 60 ft time in my '02 because as soon as I dump the clutch and the car hooks the engine bogs. You don't get the engine bog in an automatic, especially with a higher stall torque converter.

If you ran a 14.2 with a 2.5 60 ft time then a 2.0 60 ft should pretty safely equate to a 13.4 -13.5 second time and possibly quicker.

 

My car ran in the high 104.x mph range with intake and exhaust mods (street tires and stock gears). My best ET was a 13.5x with a 2.2 60-foot.

 

I wouldn't put much into the mph listed @ Beech Bend. There were stock cars running 108mph traps.

mph/ET will vary w/ the powertrain. A blower car will always have a mph faster than the average car. Like Aaron said, the high 60' will add to the mph too.

If there's one nearby, try again at your local track.
